Simple String Saver

Hi guys! I am new in the forum, first I can some speak English :P/> my from a Turkey, but I am good in the ComputerCraft. Today I want show my Simple String Saver, It's a very basic but efficency (I can write wrong :P/>) code in the down;

stringSaver = { } -- This is table for save strings.
x = 0 -- This is saved string number
for y =1,3 do -- You can change it, this give 3 string for you.
  print("Enter String: ") -- A simple Print! :P/>
  input = io.read() -- For read input
  x = x + 1 -- This add x because if x don't add 1 then x = x and last input is table[1]
  table[x] = input -- Table string number equals to input in line
end -- You know it :P/>

while true do -- Try for program all times
 print("Match string?: ") -- It's ask match string, if you write 1 then this print table[1]
 input = tonumber(io.read()) -- This translate string to number if you dont do then you get nil
 print(table[input]) - Print a your input
end -- THE END!

You can use in the Lua, this code don't have got any api, if you like it please comment to topic :P/>

I can't really see a use for this, And in the for loop you could have done this

for i = 1, 3 do
	print( "Enter String: " )
	local input = read() -- Made this local to this loop
    stringSaver[i] = input
end

Do you see what I did there? I removed the uneccessary( < pretty sure I spelled that wrong :P/> ) variable x and also made the
variable input local. Also noticed you put table in the loop, Shouldn't it be stringSaver?

you could also just drop input all together:

for i = 1, 3 do
    print( "Enter String: " )
    stringSaver[i] = read()
end

Heck, if you were adventurous you could even do this:

for i = 1, 3 do
  stringSaver[i] = print("Enter String: ") and read()
end

Yay! I'm gonna be even more adventurous with the full code! :D/>

local stringSaver = {}
for i = 1, 3 do
  stringSaver[i] = print("Enter String: ") and read()
end

while true do
	print("Table index: ")
	print(stringSaver[tonumber(io.read())])
end

It's a pretty cool program for your first released by the way.

Lol, you stored the values in the table api…

Anyways, continuing the trend!

local stringSaver = {}
for i = 1, 3 do
  stringSaver[i] = print("Enter String: ") and read()
end

while true do
	print("Table index:\n"..(stringSaver[tonumber(io.read())] or "Invalid index!")
end

CometWolf the print in your while wouldn't work, syntax error and order of operations error :P/>

blargh forgot a parenthese, i don't see any other error though?

print("Table index:\n"..(stringSaver[tonumber(io.read())] or "Invalid index!"))

Order of operations. I'd do the read, tonumber it, look it up in the table and then print "Table index: [value]" or "Table index: Invalid index!". I assume you wanted it to print "Table index: " before the read, like the other code examples.

Now that you mention it, that does make more sense :P/>
